Well, I think the difference is that programmers can deal (or at least,
try to deal) with multi-million-line programs, while mathematicians seem
to snob multi-million-line profs.

On the other hand, some programs are not read and checked enough, as
several security bugs discovered recently showed.

But nonetheless, professionnally, programmers have to work on big code
bases, and find ways to do it, how imperfectly they may be.

It looks like mathematicians are less willing or able to do so.
